<u>Answer:</u> The volume of given amount of ethanol at this temperature is 159.44 mL
<u>Explanation:</u>
Specific gravity is given by the formula:
We are given:
Density of water = 0.997 g/mL
Specific gravity of ethanol = 0.787
Putting values in above equation, we get:
Density is defined as the ratio of mass and volume of a substance.
......(1)
Given values:
Mass of ethanol = 125 g
Density of ethanol = 0.784 g/mL
Putting values in equation 1, we get:
Hence, the volume of given amount of ethanol at this temperature is 159.44 mL
The easiest answer and most relevant is because it didn't sink

Answer is: osmotic pressure.
The direction of osmotic pressure is always from the side with the lower concentration of solute to the side with the higher concentration, in this example, from solution b (5% glucose) to solution b (25% glucose).
Osmotic pressure, alongside the vapor pressure depression, freezing point depression and the boiling point elevation are the colligative properties od solution.
Answer:
Because it will cause you to urinate more
Explanation:
Salt like NaCl will turn into ion when absorbed. These ions will increase the osmotic pressure of the blood and in turn, will takes water around. If the volume of blood keeps increasing, it will increase the burden of heart to pump blood too. Ion also can alter electrolyte concentration and This condition can be dangerous if left without a response. The human body will try to eliminate the NaCl by filtering it using a kidney. But NaCl will take away water molecule so it increases the volume of urine you produce.
If the concentration of NaCl from the solution you drink is higher than the concentration of NaCl of the urine, you remove more water via urine than gain it from drinking.
